    摘要: A process and apparatus is for recycling LCO and/or HCO to an FCC unit to recover additional distillate. Spent catalyst recycle in the FCC unit may be used to improve distillate yield. A hydroprocessing zone may saturate cycle oil aromatics for cracking in an FCC unit. The recycle cracked stream may be recycled to a downstream hydroprocessing zone to avoid a first hydroprocessing zone for hydrotreating feed to the FCC unit. Additional recovery of cycle oil for recycle is obtained by heating slurry oil prior to vacuum separation.

    摘要: One exemplary embodiment can be a process for mixing catalyst in a regenerator. The process can include providing a first stream of catalyst, a second stream of catalyst mixed with the first stream of catalyst, and an oxygen-containing gas to a chamber via a distributor of the regenerator. Generally, the chamber imparts a swirl to at least one of the oxygen-containing gas, the first catalyst, and the second catalyst for regenerating the catalyst.

    摘要: The present invention relates to a process for producing metal oxide from metal compounds, in particular metal hydroxide or metal carbonate, in which the metal compound is conveyed into a reactor (25) with fluidized bed, heated there to a temperature of 650 15 to 1150° C. by combustion of fuel, and metal oxide is generated, as well as to a corresponding plant. To improve the utilization of energy, it is proposed to introduce a first gas or gas mixture from below through a gas supply tube (26) into a mixing chamber (20) of the reactor (25), the gas supply tube (26) being at least partly surrounded by a stationary annular fluidized bed (27) which is fluidized by supplying fluidizing gas, and 20 to adjust the gas velocities of the first gas or gas mixture and of the fluidizing gas for the annular fluidized bed (27) such that the Particle-Froude numbers in the gas supply tube (26) lie between 1 and 100, in the annular fluidized bed (27) between 0.02 and 2, and in the mixing chamber (20) between 0.3 and 30.

    摘要: A plant for producing metal oxide from metal compounds includes a fluidized-bed reactor in which the metal compounds are heated by a combustion of a fuel to produce metal oxide. The fluidized-bed-reactor reactor includes at least one gas supply tube at least partly surrounded by an annular chamber in which a stationary annular fluidized bed is disposed, and a mixing chamber disposed above an orifice region of the gas supply tube. A gas flowing through the gas supply tube entrains solids from the stationary annular fluidized bed when passing through the orifice region.

    摘要: An SNCR distribution grid for introducing a NOx reducing reactant into a flue gas flow. The grid is made of one or more elements which are formed by fluid-cooled tubes to which membrane pieces are attached, preferably by welding, to form conduits in between the tubes. The fluid-cooled tubes may be cooled by water and/or steam and the distribution grid is disposed in the flue gas flow. To admit the reactant into the flue gas, nozzles are provided in the membrane and the reactant is conveyed from a location external of the furnace or combustor enclosure, into the conduits so formed, and thence out into the Flue gas flow via the nozzles.
